Iron Man star Robert Downey Jr revealed on Thursday he bears no ill feelings towards Gwyneth Paltrow after she called him a "wuss".

The actress, who reprises her role as Pepper Potts opposite the 48-year-old as the superhero and his genius alter-ego Tony Stark in the third film, quipped about her co-star being a "wimp" for complaining about wearing the metal armour after she tried it on.

Kingsley, who plays the film's villain The Mandarin, said: "As a new guy, you get a bit nervous about joining these established people and this great team but they were very welcoming and very kind so it was a joy."

Hall (Dr Maya Hansen) revealed she also was "thrilled" with her debut in a superhero film.

She said: "It was completely and utterly thrilling. There's a reason why these movies are one of the most popular in the world - it's a proper Hollywood, fun film experience and it was an honour to be a part of it."
